What are Socket Countersunk Screws?

Socket Countersunk Head Screws feature a countersunk head type, which allows them to sit flush with their target housing. Countersunk screws are designed to be used alongside pre-drilled countersunk recesses. The socket head of these components makes them ideal for use alongside AccuGroup’s Hexagon Drive Bits. AccuGroup’s Socket Drive Countersunk Screws are precision rolled to achieve a general tolerances of ±0.13mm.

These fasteners can be manufactured from a range of materials, including A2 and A4 Stainless Steel, Titanium, Aluminium, Brass, Phosphor Bronze and PEEK. Chemical Blackening, Thread Locking Patches, and various other finishes are also available on request.
